Internal hemorrhoids can easily cause rectal bleeding. The main reason is the varicosity of hemorrhoidal veins. During defecation, dry and hard stools scratch the hemorrhoidal veins causing them to rupture and bleed. Additionally, due to the long-term presence of hemorrhoids, the hemorrhoidal veins become overstretched, making the vein walls thin and fragile, and easily damaged during bowel movements. For hemorrhoid-induced rectal bleeding, treatment can be administered through medications aimed primarily at reducing bleeding symptoms and alleviating the varicosity of the hemorrhoidal veins. Sitz baths can also be used to reduce swelling around the anus. If medication provides limited relief, minimally invasive or surgical treatments may be considered.

Can hemorrhoids cream be used for bleeding hemorrhoids?

Bleeding, as one of the common symptoms of hemorrhoids, is relatively common in daily life. If hemorrhoidal bleeding occurs, hemorrhoid creams can be used. Many hemorrhoid creams have the effects of stopping bleeding, reducing swelling, and alleviating the erosion of hemorrhoidal mucosa. Using hemorrhoid cream can provide limited relief for mild hemorrhoids, especially in reducing bleeding symptoms. However, if the bleeding is substantial or frequent, the effectiveness of hemorrhoid creams will be relatively limited, and it is necessary to seek timely medical treatment at a hospital.

How to alleviate hemorrhoidal bleeding

For hemorrhoid bleeding, it is first necessary to determine the degree of bleeding. If it is mild hemorrhoid bleeding, it can generally be managed with the use of hemorrhoid suppositories to compress and stop the bleeding. If the bleeding is more severe, oral hemostatic medications can be taken. If relief is still not achieved, it is recommended to seek treatment at the hospital's colorectal surgery or gastroenterological surgery departments. If hemorrhoid-induced bleeding occurs frequently and with a large amount each time, it is advisable to consider hemorrhoid surgery as soon as possible. Hemorrhoid bleeding is caused by the tortuous dilation of the inferior rectal venous plexus, which can be injured and cause bleeding either in cases of hard stools or when hemorrhoid symptoms are severe. In the operating room, the diseased vessels need to be removed to fundamentally resolve the cause of the bleeding.

What should I do if hemorrhoids are bleeding?

Hemorrhoids that bleed should be treated to stop the bleeding as soon as possible. The common clinical symptoms of hemorrhoids mainly include localized bleeding, repeated prolapse of the internal part of the anus, and pain. Early bleeding can be managed with oral hemostatic medications, application of hemorrhoidal creams to the anal area, and use of anal plugs with thrombotic agents for comprehensive treatment, for minor bleeding. The symptoms can be relieved with medications. However, if the bleeding lasts long or if there is a greater amount of bleeding from mucous membranes and the bleeding points are fragile, further surgical ligation may be necessary to stop the bleeding. Common surgical methods mainly include excision of mixed hemorrhoids, internal ligation, or hemorrhoid banding procedure, and can also be combined with submucosal sclerotherapy injections.

Can hemorrhoids suppositories be used for bleeding hemorrhoids?

Hemorrhoidal bleeding can be treated with hemorrhoidal suppositories, which can alleviate circulatory disorders around the anus, reduce inflammation of the veins, and prevent the worsening of hemorrhoids.

During the treatment period, it is important to maintain a light diet, avoid spicy and irritating foods, drink plenty of water, eat fresh vegetables, ensure smooth bowel movements, and clean the anus after defecation to prevent infection. Active medication or other methods of treatment should be pursued.

Hemorrhoids bleeding symptoms

Hemorrhoids bleeding during bowel movements is actually a common symptom in clinical settings and is a typical symptom of hemorrhoids. This bleeding generally occurs during defecation, sometimes soiling the fingers with blood, and can also cause a spraying type of bleeding. Furthermore, excessive exhaustion, irregular eating patterns, staying up late, and heavy alcohol consumption may exacerbate this bleeding, which are typical symptoms of hemorrhoids. The blood from hemorrhoids is usually bright red, and this condition is intermittent in nature, often not mixing with the stool. Thus, the bleeding generally stops after defecation ceases, and this condition can worsen with the patient's bowel movements among other issues. Additionally, if bleeding of a different color occurs, it may be caused by upper gastrointestinal bleeding, thus it is important to distinguish this from hemorrhoidal bleeding.
